A pin retaining force (a pin torque of the base) Fe after use by which the base body retains the pin is at least 0.08 Nm after the fluorescent lamp is burned for a rated life, and a rate Fe/Fi of an initial pin retaining force Fi by which the base body retains the pin before use of the fluorescent lamp and the pin retaining force Fe after use is at least 0.66.
